A cervical dilation device (100) for dilating a patient's cervix while providing means for easy entry through the patient's cervix and into the uterus. The cervical dilation device (100) comprises an elongated hollow tube (102), having an inflation bulb (104), a means (106) for dilating the cervix. In the preferred embodiment, the tubular balloon (106) has an outer surface(108) and an inner surface (110) which define an access aperture (112) and are connected by supports (114). Upon inflation the outer and inner surfaces move together, enlarging the access aperture. In an alternative embodiment, a second tubular balloon (502), connected to a second catheter (508), is positioned around the first balloon such that the inner surface of the second tubular balloon is integrally connected to the outer surface of the first tubular balloon. The outer surface of the second tubular balloon (502) is perforated for drug delivery. |
